XLR Connector -- Also known as Cannon plug, widely used in microphones, musical instruments and other devices, can be used for analog audio signal transmission, also can be used for digital audio signal transmission. XLR to Screw Terminal -- This XLR 3 pole dual channel male solderless terminal adapter cable has two connecting parts, connector 1 is a XLR male connector, and connector 2 is a solderless 3-pin screw terminal, connected by a 33cm adapter cable. Wiring Details -- The XLR connector usually has three pins: 1. ground/shield (Ground), 2. hot end (+), and 3. cold end (-). This design effectively counteracts external electromagnetic interference and ensures signal stability and purity. Easy to Connect -- No need for solder and soldering tools, just use a screwdriver to fix the screw terminal part to connect. The XLR plug portion is made of metal with sturdy structure, suitable for frequent plugging and unplugging and long-term use. Widely Used -- The 3-pole XLR adapter terminal cable is widely used in music production, performance, broadcasting, and film and television post-production, especially between microphones, mixers, audio interfaces and other devices. Due to its balanced transmission characteristics, the XLR interface can provide a higher signal-to-noise ratio than unbalanced interfaces, which is suitable for professional fields that pursue high sound quality.
